## Find your app

## Questions

### Does Never for previews delete my messages?

No. The preference concerns notification content. Your conversation, attachments and account remain separate things to inspect. Use an ordinary sample to verify the locked and unlocked notification views. If you want deletion or access removal, read the relevant workflow before taking action; neither follows automatically from a preview choice.

### Does When Unlocked mean nobody can see message text?

No. It is an unlocked-condition preference, not a guarantee that every person or device lacks access. Check the behavior on your phone, including what happens while it is already unlocked. Inspect the Messages application and any other signed-in devices independently before deciding whether the setting addresses your concern.

### Can a recipient still keep an attachment?

Changing your notification settings does not recall a copy already received or saved by another person. Review the sharing path and known destinations separately. Treat a conversation, a saved Photos item and a recipient download as different copies with different access controls, rather than assuming one local change governs them all.

### Is Hide Alerts the same as locking Messages?

No. An alert setting concerns notification behavior; an application lock concerns opening an eligible application through device authentication. Inspect the supported controls on your installed release and test each one. A muted conversation should not be described as a separately password-protected archive merely because it no longer interrupts you.

### Will this change notifications on my other devices?

Do not infer another device's behavior from this iPhone. Check the settings and account on each device that receives the conversation. An ordinary test message helps establish what appears where. Keep those observations separate from claims about cloud retention, recipient copies or which account sessions are still active.

### Should I delete a conversation to test previews?

No. You can test a notification preference with a harmless sample conversation. First change the display setting, then inspect the relevant screens. Deletion has different consequences and may affect copies or recovery. Do not introduce that risk when your goal is simply to verify where notification text appears.
